Abstract
C7-C12 secondary alcohol esters of cyclohexanecarboxylic acids are especially useful as plasticizers for PVC and other plasticizable polymers. In embodiments, these plasticizers are useful in plastisol formulations to help improved processability of flexible PVC material. In other embodiments these same plasticizers can be used in blends with other plasticizers to improve processability. In preferred embodiments these same plasticizers can be used to prepare flexible PVC compounds with enhanced low temperature flexibility, low toxicity, and improved resistance to outdoor aging.
